Her cake is beautiful & as soon as I saw it, I wanted to try it. I tried it for a family gathering for my 3 year old's birthday and I wanted to do it the quicker and easier way. So, today my friends, I'm going to share with you the easiest way to recreate the rainbow cake....

With store bought cake mixes and store bought frosting. Here's what you'll need:
(I only used 3 of those frosting containers for mine)

1. Start by making the cake mixes as directed on the box (use WHITE cake mix- not yellow, and only egg whites or the colours of the cake won't turn out as well).

3. Bake in round, lined cake pans (watch carefully since they are smaller than the mix expects, and will be finished sooner).

4. Take each cake out of its pan & let cool. Then wrap and put in the freezer. (I did mine overnight just because that's what time I made mine, but you only need to leave it long enough that the layers are easier to work with than soft cake)

5. Plop the first layer of cake on your place (icing underneath will "glue" it in place) and frost the top of it, then add your next layer of cake, frost the top, add the next layer, etc. until it's all assembled like so:

6. Finish frosting the outside of the cake (be generous with your frosting between layers & on the outside, to prevent crumbs showing through on the outside, and to make it look cooler when you cut it ;)

You can leave it plain or add decoration to it. Here's what I did with mine:

And here's what the slices look like:

Isn't it pretty? :) I was so happy with the way it turned out! Someday I'd love to make Kaitlin's deluxe version, but for this occasion, the store-bought mixes & frostings did the trick!

I made Whisk Kid's rainbow cake for Jessie's 5th birthday! It was really fun to make and turned out stunning, but I will admit my family didn't love the Swiss Meringue Buttercream, especially the kids.

Hi Jayma, I used gel food colouring which definitely helps make the colour richer. I just kept adding it until the batter looked about the colour I wanted & that worked great! (Also, using a WHITE cake mix with only egg whites makes a big difference for the colour showing through)

I Love this! We just posted our 2nd Kitchen Fun and Crafty Friday Link Party today and would love for you to share this! http://kitchenfunwithmy3sons.blogspot.com/2012/02/kitchen-fun-and-crafty-friday-link_16.html

I just made a cake like this and used lemon cake mix. I was a little worried how the yellow colored cake mix would affect the colors, but it turned out great. I did use food color from a professional cooking supply store, but just letting you know it can work.

It has been over a year now since I made the cake & I haven't done it since! I can't say I remember for sure! I would suggest assembling the cake a couple of hours before you want to eat it (or earlier), but I'm not totally sure!
